Title: Inflation-free tire structure

Abstract: An improved inflation-free tire structure for use on light duty vehicles, such as mowers and wheel chairs, has a crude tire, a pair of wheel discs and a bearing. The crude tire is provided with multiple radial plies that are extended over and wound around the wire beads disposed on inner parallel peripheral rims of a tire and further led to the middle or bottom portion of the rubber side walls of a tire so that the strength of the tire is reinforced. Each wheel disc provided with a flanged rim has a central through hole with four holes disposed on the periphery thereof so as to permit the bearing to be guided through the two wheel discs and fixed in place. The tire has a central hole with which a wheel disc is in snap engagement. The diameter of the rim of the central hole of the tire is smaller than the diameter of the flanged rim of a wheel disc so that the tire can be sealedly engaged with each wheel disc in assembly.
